Step by step we walk on the hard granite blocks, slabs and pebbles of Siza’s FAUP, Serralves Foundation and Avenida dos Aliados as well as Barbosa & Guimarães' Viela do Anjo. From the soft pink stone of João Carreira’s Teatro de S. João and the grey stone and soft green grass of Eduardo Souto de Moura’s Trindade Metro Station, we jump over to the hard red brick of José Manuel Soares’ Porto Planetarium. At the end, we walk away from the sea at Manuel de Solá-Morales’ Passeio Atlântico and towards the mixture of steel, glass, ceramic and travertine pavements at OMA’s Casa da Música.
